What to do first

1. The in-game mailbox. Everything from pre-registration was delivered there. Work out exactly what you should have received with the launch mailbox tool; the claim window closed on August 29, 2026, 23:59 KST, and anything unclaimed then was forfeited.
2. Check it against the milestone list so you can tell whether something is missing — see our pre-registration rewards guide.
3. Learn the basics with our beginner guide and check the tier list.

Confirmed with the launch announcement

• Pre-registrations surpassed 2 million — everyone gets 100 Pick-up Cookie Cutters and 100 Pick-up Pet Gacha Tickets as a bonus on top of the milestone table.

• Two core modes were confirmed by name: Crumble Dungeon (challenge bosses with every Cookie you own) and the Arena (compete with other players’ builds).

• Everything you earned before launch — sign-up rewards, milestone rewards and mini-game prizes — was delivered to the in-game mailbox after launch, and it all expired: the window closed on August 29, 2026, 23:59 KST (GMT+9).

We’ll add the server list and any launch-day maintenance windows here if they’re announced.
